Abstract

New controlled retracting gasifying agent injection point process for UCG sites. The process consists of a retraction of the gasifying agent injection point achieved by gradually plugging the tubing ends either by pneumatic injection of inert granulated material with a thermosetting binder, or by closing valves set at regular intervals inside the tubings.
